    This changed neglected the use of counters by the Dataflow runner, which is used to prevent
tests for spuriously passing when a `PCollection` is empty (as well as just diagnostic printouts).
    
    Obvious fixes for that revealed probable bugs in the in-process and Spark runner, as well
as tests that happen to work with `PAssert` but are actually unsupported.
    
    A proper long-term fix is underway to address all of the above. In the meantime, this
commit rolls back the changes to `PAssert`.
